Abstract
Trocar components and methods of use are described, wherein the trocar components are configured to provide access to intraperitoneal space via the rectouterine pouch to surgical tools, which optionally include one or more surgical robot members. The surgical tools are optionally 5 mm or more in diameter. In some embodiments, a cannula part has a lumen sized to provide to a plurality of the surgical tools simultaneous transvaginal access to the intraperitoneal space via the rectouterine pouch. In some embodiments, an incision sized to receive a distal aperture of the cannula is created, optionally using one or two dilators. The dilators are sized to create (optionally starting from a puncture by a needle 2 mm in diameter or less) an oblong aperture. In some embodiments, the oblong aperture is at least twice as wide across a long diameter as across a short diameter.
